Invisible Network Card?!?

I was connected to the internet via my DSL modem a few days ago and everything was working fine. However, today all of a sudden my internet does not work. I was trying to determine the cause of the issue and got an error message that my computer does not have a network card (which it obviously does as it's on the mobo). I checked device manager and do not see a network card listed (but it does show my 1394 card). I don't know if my network card is damaged? or maybe it's got some sort of driver issue? (although I ran the new hardware wizard and it did not find any new hardware). Any suggestions are greatly appreciated (OS = XP Media).

Re: Invisible Network Card?!?

There must be a motherboard failure at the network adapter, because if there is non showing, even with an exclamation mark then there is according to XP no network adapter fitted. Go into the bios (press F2 or Del on start up) and when in the cmos settings, go to advanced and look at the harware menu; and in there should be your onboard network adapter listed as either enabled or dissabled, if dissabled enable it, if not showing at all then there is a motherboard fault, as even if the motherboard driver wasnt working XP's own default driver would see it. all is not lost though because if you don't see it listed in the bios you can fit a PCI ethernet card very easily and cheaply which will fit in one of your spare PCI slots. See below.

This is only a problem with the firmware of your modem/router that you need to update it, because a network device like a modem and router that is working fine for severla years and suddenly stop working you just need to update the firmware of it and it should be working fine again, to update the firmware of the modem/router just need to call the manufacturer for that....

Hope that helps.........

How can i connect my desktop computer to the internet plz i need someone to help

Currently, the most common way to connect a desktop system to the internet, is by using the network jack to connect to a broadband cable modem or DSL modem. To do either you must have the service from either you cable provider or phone company (For DSL) and have the modem device for the service. Fees run $20 to $50 a month depending on speed you subscribe.
You connect the device to the system using a CAT5 network cable to a RJ45 (8 wire telephone type jack). Some Cable/DSL modems also have USB connection capability for the few systems these days that do not have a built in RJ45 connector To use them, you install the associated software, then connect the USB cable when prompted.
If you don't have Cable/DSL then dial up telephone modem is the next option, this requires a telephone modem that has an RJ11c telephone cord jack connection, most current computers only have a telephone modem as an option, but they can still be bought for around $20 and you will require a dial up internet service (Few remain, one is Netzero in the USA)

I have a used compacq 530 but do not know what is missing because i cannot get it to hook up to the internet

Possibly if you gave more information .....does it have a network card installed, is the network card "enabled" in the hardware settings, does the network card have correct drivers ? ( no yellow question mark beside it ) Do you have an internet provider and account ? Is your internet high speed or dialup, if it is dialup, do you have a modem installed - with correct drivers ? Is it working - do a modem query to see if it responds ?
If using a network card and cable or DSL internet, is the cable connected from the PC to the cable or dsl modem ? Is the cable or dsl modem plugged in and the power and wan light on ? With the little bit of information you have given, it is not really possible to give an exact answer to what the problem is.

Cannot connect to internet. I had internet connection over telephone modem before Hard drive crashed. I replaced HD and could not connect to internet. Dell was no help at all. I signed up for Verizon DSL...

I bet you are using the phone modem that canme in your machine. You need to connect the Network card ( Ethernet Card) and make sure the drivers are working. Find it is System, Hardware, device manager, look for ethernet.
Connection icon and see if the netcard driver is installed.Connect the cat5 cable that was sent to you with the DSL modem box. It chould be a yellow cable... It only fits one way and in a maked plug on the DSL modem and into the network card in the computer. Everything there after should go automatically.

Internet no longer working, but internal network is fine.

i agree with all the above.. it's definately clear as mud how the network is designed and or funtioning. The machines connected to the wireless d-link router.. are they via cat5 inthe wired ports or wireless ? is the server the machine thats connecting to the switch and wiress router and modem? i'd say reset all switches modems routers and machines.. shut them all down.. then fire the cable modem, then the wireless router then the desktop switch then the server, the workstations and the one lonely wireless.. run "ipconfig /all" on all machines and if they aren't all sharing common ips and access, provide the results here for further investigation.

My internet speed is slow.I connect it via bluetooth.

Internet broadband connection is much more faster because it is directly connected via physical connection from the modem (typical setup for home use). But now a days wireless internet can now compete with DSL thru a 3G/HSPDA network. In our country we can have a maximum bandwidth of 2.5Mbps using 3G wireless network.

Yes you can speed up your connection using your phone as a modem but you need to consider some aspects.
  • your phone is a 3G capable phone
  • you have 3G network signal that an indicator "3G"can be seen next to the signal meter of your phone.
  • your network provider has 3G services.
What happen to you most likely is that your are connected using only a GPRS/EDGE. This is equivalent to a dial-up with maximum of 56kbps transfer rate. There is a great gap between the two if you compare it.

I already tested mine with maximum receive/downlink of 2,501 Kbps. I was really amazed.

Hope this things help you. If it does, please rate me.

A recent mac laptop with Tiger & bootcamp/win XP will connect to the internet via a Netgear DG834G adsl modem with ethernet cable in tiger & XP but only in xp with wireless. Any advice? JL

If I understand you correctly you have an Intel based MAC, with the boot-camp boot manager, so you can choose to boot either from the native MAC OS or from Windows XP.

The system works fine from the MAC OS, but the (wired) ethernet does not work from XP.

1) When you boot into XP mode, the XP operating system is in
charge and the MAC OS is dormant.

2) Check the XP device manager to see if the ethernet NIC
(network device) is properly installed and if the device
drivers are functioning.

From Windows XP:

Right click My Computer ==> Properties => Hardware ==>
==> Device Manager ==> Network Adapters =>
==> Your network controller

Right click on your network controller ==> properties

Check the device status !!!

2) If the device is NOT working properly, you may need to
download and install a device driver for this card.

3) If the device IS working properly, you may need to run
the NETWORK SETUP WIZARD from the control panel:

START ==> Control Panel ==> Network Setup Wizard ==>
==> Next.

4) Assuming you are connecting to DSL with a login password,
use the: "My computer connect to the internet through a
modem" option.

If your DSL is always on, or if you use a local router to
connect to the DSL modem (the router does the work)

Then you choose the: "My computer connects to the
internet through another computer or a residential gateway"
